I am sitting right now playing with a piezo speaker for a fun project I want to make with my 5 year old daugther. I tried different projects I found, like this one, but then I found yours! It was by far the easiest as the christmas tunes was already coded.

It's running now and works fine. Although without the speaker and LEDs, I am just running it with a piezo speaker alone in continous mode.

However, I want to add the RGB LED I have in my drawer

Thanks a lot and Merry Christmas!

PS. Is it possible to change the volume, making it play a little more quiet?
